16 Claims.-

This invention relates generally to a table or cabinet structure particularly adaptable to house and support heavy volumes such as catalogs, telephone directories, or the like, in such a way that they are readily accessible for use and when not in use may be moved with the utmost ease to a position beneath the table top out of the Way of the user.

Our invention is of particular utility in large department stores or large olces where it is desirable to have at hand for immediate access a large bulk of printed information; As an example, telephone offices or sales oilices of large industries such as automobile parts distributors nd it necessary to have available at a moments notice information contained in catalogs or similar periodicals, which information can be readily placed at the disposal of the customer. It is this need that the present invention meets.

Past efforts have been made to devise a support which would accomplish the functions of our invention but these efforts have heretofore resulted in structures containing numerous disadvantages to the user, such as the dililculty of operation and the relative expense of manufacture. The present invention is directed to a design of extreme breaking or otherwise mutilating the surface of the top of the said table or cabinet structure so as to permit this function. The smooth unbroken flat top of the table structure alorded by our invention obviously lends itself to many uses-other than merely a cover for the container of the volumes referred to, since the said top has at the same time considerable utility as a desk or commercial counter. Those disadvantages which accrued to the many devices of the past illustrating catalog cabinet supports have been obviated by our invention. Heretofore, among other disadvantages, the top of the cabinet support had to be broken in many places or in the alternative the said top could not be horizontally positioned thereby preventing its employment for any of the other uses hereinbefore mentioned.

Another advantage of our invention is the great (Cl. S12-34) ease of manipulation of the units contained in the cabinetsupport. -These units, and for Ypresent purposes catalogs may be used as the specific example, are simply lWithdrawn horizontally, to-

wards the user-,Troni underneath the cabinet top and-then swung circularly in a arc to a complementary horizontal position on thetable top without undue effort upon the part of the user. The entire manipulation is accomplished With great facility, the weight of the volume being at all times suitably supported.

An additional'advantage is that the features of the present invention permit the sizeof the cabinet'support' as a-whole to be readily varied from one containing, perhaps, a single volume, to as many units as are needed in accordance with the requirements ofthe user.` Y

Our invention also features unique meansA for Vthe ready detachment of any single volume from its binder', and the ready insertion of any alternative or additional volume to an empty binder.

A'further-advantage of the invention is the use of af binder which is swiveled upon therpivoting arm, hereinafter described, so that the binder, after being placed upon the top of the cabinet 'support can, in its entirety, be revolved to any desired position upon the top of the cabinet for ease of perusal from every angle. y V A stillfurther advantage is that our invention is vsodevised that it may be utilized upon almost any conceivable type of table or cabinet structure. In other words, it is not necessary `that thecabinet per se be fabricated as an integral part of the catalog holding means, the latter being adapted to be affixed to various types -of preformed cabinets with little or no alteration of the latter. In

this respect, our invention vnot only aords great economies to the user but is much more adaptable to the various requirements necessitated by differentbusin'esses. v

It will be apparent,- from -a reading of the following description, that this invention has many other advantages and uses not recited inthe foregoing, all of which come within the scope of the present disclosure.

For a better understanding of the elements of our invention, and their inter-relation to produce the results desired, reference is made to the accompanying drawings in which: Y -1 AFigure l is a perspective of the assembled units ofthe invention 1 Y Figure 2 is a cross-section taken upon Figure 1;

Figure 12 is a detailed plan View of Figure 10 illustrating the mode of attaching the swivel plate and Figure 13 is an end perspective of the swivel arm or carrier illustrated in Figure 10.

Referring more particularly to the drawings, the cabinet structure is generally indicated at I;. Preferably it has an unbroken top 2, the same surmounting any of the usual types of sidings 3 and backing 3a; which is supported by suitable legs 4 of the usual construction. Aixed to the underside of the top 2 are a series of grooved slides 5 which may be made of either metal or Wood. As indicated. in Figure l, these slides, positioned transversely tov the cabinet top, are merely strips, rectangular in cross-section and having longitudinal grooves. E on opposed sides thereof. The grooves or channels may extend throughout almost the entire length of the slides but are not projected through those` terminal ends of the same facing the user, these ends being closed, for purposes` hereinafter described. The aforesaid grooves or channelsv 6 are of equal depth on each side, their formation being more particularly illustrated in Figure 7, where they are shown in broken lines in cross-section. The cabinet may be partitioned any suitable number of times by a series of partitioning members 'I which, in the assembled view of the invention illustrated in Figure 1, are affixed to the underside of the slides hereinbefore referred to and are supported atvtheir lower extrem-ities by a transverse frontal member 8. The referred to slides 5 are adapted to receive a swivel arm or carrier 9, more particularly described hereinafter, which in turn provides support for binders l0, and for retaining members II, adapted to maintain in place any type of catalog or similar heavy volume, such as that illustrated at I2. The binders I0 may be hinged to the carrier 9 by any suitable type of hinge I4 so that access to the Volume itself is facilitated. e

Referring to Figure 1, when the invention. is shown assembled for use in an appropriate table or cabinet structure, the swivel arm or carrier,

with the volume to be supported in place, isV

shown in its several positions for use. For instance, most of the volumes such as that generally indicated at A, are illustrated in place in the normal position of the same whenV not in use, that is, supported horizontally inside the cabinet -and within the several partitions. At B the volume is shown withdrawn from the cabinet to the extremity of the aforesaid slides, it here being in position for rotation by the user to the table top. At C the carrier and supported volume has been partially swiveled to its position atop the table structure; and at D the carrier, and accompanying Volume, has assumed its nal position fiat upon the table top with the volume I2 and accompanying retaining and swivel plate partially rotated with respect to the said arm or carrier.

It will be seen that the swivel arm or carrier 9 is provided with a hooked or U-shaped end section i3, the latter having means movably interconnected with the aforesaid slides as to enable the entire arm 9 to be inserted within or withdrawn from the underside of the table by horizontal movement of the said arm along the grooves 6. In Figure 2 the carrier or swivel arm is indicated in position within the cabinet, and in dotted lines, its relative position is also indicated at 9c when the arm is withdrawn from beneath the table and swiveled upwardly and arcuately to a position upon the top of the table. In this position, the U-shaped bent over end section of the carrier is indicated generally at I3'a.

The structure of the carrier arm 9 canbe better understood by reference to Figures 3 and 4 wherein the structure of the arm is illustrated in more detail. Although the said carrier may be fabricated as a single unitary structure, it is preferably constructed of two segments. The segment l5 has a curved end as at Il which curved end is designed to t the complementary segment i6. The opposite end of the arm I5 is provided with a face I8, suitably beveled at a 45 angle to the longitudinal sides of the arm, and thereby useful as a support for some form of label designating means such as that indicated at I9, Figure 3. The portion IS of the swivel arm or carrier is provided at one end with a rounded or semi-circular surface 2i) permitting smooth and easy rotation thereof (such as when the carrier is in the position shown in C, Figure l); and also with dowels 2i or other rod fixtures positioned adjacent said surface 2t such as would be suitable for maintaining the arm l5 in position for reciprocal and rotational movement in the aforesaid slides 6. The two referred to segments of the swivel arm or carrier S are joined together in any practicable manner, here shown as through the use of a common type of screw 22, although wooden dowels or other obvious expedients may be utilized. It is to be observed that the position of the line of separation. between portions I5 and I6 may approximate that shown at 23; and that the distance between the parallel inner sides or faces of members I5 and l may be varied. Where the arm isof wood construction this variance inay be accomplished by the insertion of shims or inserts of the desired thickness between these members at their juncture.

The purpose of permitting variance in the distance between the horizontal sides of members I5 and I5- is to permit adjustability of the arm to meet various requirements. For instance, the thickness of various table or cabinet tops will vary, and the said distance between segments of the swivel arm must accommodate the said thick.- ness, when the arm is positioned for use, as shown in Figures l and 2. Also, in some cases, itmay be desirable to have drawers or shelves of some type immediately adjacent the underside of the cabinet top. The distance between the intervening segments i5 and I6 can be varied, in such cases, to accommodate the combined thickness of the cabinet top and such drawers, so as to permit operation of the carrier without interference with the same.

It will also be noted that the outside of said segment l5 adjacent rounded surface 20 is flat throughout its length. This surface, indicated at 26, is parallel. with segment I5 and of such length that it provides a support to maintain the swivel arm in horizontal, sliding position, prior to rotation to the table top. For instance, referring to Figure 1, when the swivel arm or carrier, .with binder attached, is in position shown at B, it will be supported in that position by weight of the volume being transmitted against the under side of the top, through segmentV i6, and, of course its face 26, the latter providing an appropriate bearing surface. Thus, no matter how far the carrier 9 be extended, it will be supported as shown, the binder being completely suspended from the top, and not resting upon any underneath support.'`

As stated, the grooves 6 do not extend throughout the complete ends of the slides 5. That end of the slide towards the user is closed to provide a bearing surface for the carrier when rotated, and of course, to prevent complete withdrawal of the carrier fromthe grooves. The opposite end of the grooves 6 lmay also be terminated at such a point that when the swivel arm or carrier is pushed longitudinally into the cabinet structure between the'said partitions, this closed end will prevent contact of the far end of the carrier with thebackof the table structure. As shown in Figures 2 and 8, theend of the said carrier is shown adjacent the back wall 3a of the cabinet structure.' `In any event the binder i0 (Figure 8) does not contact the back wall and is slung intermediateV the ends of the carrier arm so as to be completely protected from damage. In orderthat the arml I5, when withdrawn and superimposed upon the table in position for use does not mutilate the table surface, the end thereof may be provided with rubber mountings or bumpers such as those shown at 24. To further facilitate ease of operation of the arm it may be equipped with a suitable hand hold upon vthe underside thereof.

Means. for maintaining a volume in position, enabling the latter to be easily attached to and detached from the swivel arm or carrier, already described, are illustrated in Figures 5 and 6. A retainingv plate is Vstamped out of a suitable metal or other material, and preferably provided with strengtheningribs 3 I, which ribs lend additionalstrength and rigidity to the plate. The latter is further provided with two bent up members 32 and 33 as supporting Vmeans for the retaining rods. The end members 32 and 33 are each provided with two slots 34 and 31, and intermediate these two slots, two holes 35 and 36. It is' appar ent that the'retaining rods 38 can be inserted into the said slots and holes and retained therein by the use-of any common expedient such asa bolthead-on one end and threads to retain a'bolton the opposite end. We have found that rods-in the nature of bicycle spokes are extremely suitable for the described purposes, since they are of .great strength and are provided with a head `at-fone end, and threaded at the other, making them particularly vadaptable to the aforesaid purposes. The openings 34 and 31 are slots, as stated, in preference to mere round apertures, since slots permit adjustability of the two side retaining rods to various optional positions, dependent upon the nature of the volume to be -retained in the binder. If preferred, all of the aforesaid openings'may be in the form of slots'.

The retaining plate 30 is designed to t into a swivel plate 40, which is also made of stamped metal, the sides of which are bent over towards the center of the plate as at 4I and 42, to form two side channels, of suiiicient width to accommodate the thickness of retaining plate 30. This swivel plate is also provided with intersecting strengthening `ribs 43, stamped into the metal, to add to the rigidity thereof. It also contains a centrally located opening 44 through which is placed a swivel bolt or screw 45 adapted to retain the swivel plate firmly, but rotatably, in position upon the arm l5. It will also be appreciated that the retaining plate 30 is of such width that when it is inserted into channels 4I and 42 it will flt sufiiciently snugly to be retained in position therein but not so tightly as to prevent manual withdrawal. kThe assembled swivel plate and retaining plate mounted upon the swivel arm in the manner hereinbefore described, are shown in Figure '1 where it can be readily appreciated how the provision of channels 4l and 42 maintain the retaining plate in position but enable the user to withdraw and reinsert the said plate with great ease;

From the foregoing description, the operation of our Vinvention may be readily understood. With the swivel plate 40 rotatably mounted upon the carrier or swivel arm as described, the re. taining plate 30 is withdrawn therefrom. The volumeV to be mounted is opened and rods 38 inserted between the cover and pages thereof, then secured in position in the respective holes 34, 35, 36 and 31. The retaining plate is then mounted upon the swivel plate by its insertion into the side flanges 4l and 42, and with'the carrier slidably engaged with the grooves 6 a described, the unit is readyfor use.

, We Vhave found also that in the fabrication of parts in the manufacture of our invention, it is sometimes desirable for purposes of expediency and economy to make theslides or trackway, carrier arm, and accompanying` units, of plate metal in preference to the structure hereinbefore discussed, the modification of our invention now to be described being more readily adaptable to various types of table and cabinet structures.

The trackway may be fabricated from angle iron as shown in Figure 9, the same being generally illustrated at 50. The trackway may be provided with suitable apertures for the insertion of mounting screws, whereby member 50 may be aixed to the underside of the top of the table or cabinet f support. To avoid interference with roller 10', hereinafter described, these apertures are preferably located along `the sides of member 50, as shown. It is provided with two sides 5l formed at right angles to its base and these terminate in U- shaped channel members 53. These channels 53 are designed as recessed tracks for the reception of rollers 51 mounted upon the swivel arm or carrier 55. In order to prevent the aforesaid rollers vfrom` being disengaged from the channels or tracks 53, we have found it expedient to bend over two flaps 52,the same being integral withthe sides 5|. These naps are in the form of stops and` since they block each of the channels 53 they serve the function of preventing the rollers referred to from running off the trackswhen the arm is pushed towards the user, preparatory to swiveling itin position upon the cabinet top. Similar stops may be fabricated at the opposite end of the trackway 5B, to limit, as desirable, the longitudinal movement of the carrier arm 55. When'such trackway is employed we utilize a 7. swivel. arm or carrier also fabricated@ from plate or angle ironr which. is particularly adaptedl for insertion and reciprocal movementztherein. The carrier-illustrated in Figure is' composed of. two sections 55 and 55 corresponding toy the two sections I5 and I S of the modification previously described. Section 55 is a longer unit and provides the base for the swivel plate and accompanying retaining rods. It is comprised of. two sides 51 and flanges 58, designed` to addstrength and rigidity to the arm, and as' also will be seen, to provide appropriate channelsl adapted to receive one -end of they complementary section 56.. One end of section 55 may be beveled as at59 to form av suitable support for a card designator4 80,. and, as l'iereinbeiore described, theA samei end is usually provided also with rubber' stops 61 to prevent damage to the table top when the carrier is swiveled into position for use upon the top of the cabinet structure. tion 55 has portion 6 formed at right angles to the main body thereof, for purposes hereinafter described. As a means for maintaining the swivel The opposite end of secplate in position, sectionl 55 is also provided with f a suitable circular opening 52 having a keyway comprising transverse slots (i3v bisecting the same for the reception or a locking pin.A Section 5E, similarly fabricated of angle iron or plate metal, is comprised of tivo legs. 65 and (i6V disposedy at right angles with respect to each other. The shorter leg 55 is adapted to be inserted into its counterpart 64 in section 55. The other leg 86 is tted with rollers 67 rotatably mounted uponA a suitable bearing 68 and designed to revolve in the trackyvay already referred to. Leg 66' is' also made with a rectangular opening orsloti 69 providing space for the insertion of an. additional roller 19. The latter may be rotatably mounted upon a bearing supported in any approved fashion such as by bending down flaps at each end ofV the rectangular opening 59 and mounting a bearing pin therethrough. WhenV the carrier is inserted in the trackway, roller 1G is adapted to bear against the under surface of member 5U, aixed to the under side of the top'of the cabinet structure, and, in conjunction with the rollers 6'1` which are in engagement with channels 53, support the carrier for reciprocal horizontalmovement in the cabinet structure. Y.

Reference to Figure 153 will indicate that the two verticali endportions of'sections 55 and: 562 as at, 8B and 8l respectively, are so made astobe interi'itted. In other words, verticali section 80 i's of a slightly larger crossfsectional lengthl and width so as to accommodate the insertionof sec'- y tion? il I, the respectiveV sections thereby being slidiably engaged. Section 8l?? is preferablymade with grooves 8E' also adapted to snugly encompass grooves 83 of section Sli, which are'of a slightly smaller size, in such` a manner that theseV grooves not: only lend rigidity tothe respective" section-s but form guideways so that sections` 80 and'8`l may be intertted as described with relative-ease. After engagement ofthe two sections, they are maintained in place by 4some "simple expedient such as a slot and bolt connection'. Slots 84 in member 8|. are designed to receive bolts 85, the latter being inserted inf-section 8Bi through appro'- priate apertures. After intertting the two' sections in the same manner indicated; and adjusting the distance between members 55 and 5E, the assembly is maintained in` the desired position by tightening the aforesaid bolts 852. In employing )the method of manufacture and' assembly just deu.

scribedrwefnave lfoundit possible touse: one fplate as both a swivel and retainingl plate, and employ af'simp'le locking mechanisml to securev this rplate in place upon carrier 55. The plate 'l5 (Figure 121') is generally of.v stamped metal with. two ver-l tical ends 'I2t and 'I3 constructed as a support forI the typev of transverse rods '16, as hereinbefore described. A. locking. pin 'Il is centrally located in this plate and may be permanently affixed thereto by weld-ing, friction grip', or other suitable media, in the position shown in Figure 11. It has a head 78 and is also provided with twol projec-t tions 19, of sui-licient length to be inserted Within the previously described slot 63. After insertions if the plate 15- is given'` a quarter turn: it is ape parent that the projections 19 will assume the position shown in dotted lines in Figure l2, theres by maintaining the plate 'l5 in position upon the swivel arm. Obviously projections 't9 may be formed at such a distance from the head 'f8-kas toiit snugly over the base of the swivel arm. when the locking means is utilized, maintaining the re tai-ning plate rmly therebetween in engagement with the swivel arm or' carrier, but not so tightly as to prevent rotation-,. with comparative ease, of plate 15, at the des-irey of the user.

It is apparent that in this modification of ou: invention wei have providedv means' whereby 'the entire volume support, including track-way, carrier andy accompanying apparatus, may be aiixed to almost any conceivable type of tableor cabinet structure Without alteration of. the latter. For instance, the trackway 541,.when'` disposent as shown in Figure 9,4 may' be readily securediby obvious@ expedients to the underside of the top off such. a structure. After adjustment of the distance between its parallel sections to accommodate the thickness of the said top,. the carrier 55 is placed in position in the'trackway. A` bookorvolumeis secured to the swivel: plate t5 the manner'heretofore described, locking pin 'H fitted. into itskeyway and the plate given aquarter turn to rotate and secure projections 'l-9 in the position shown Figure 12. Arm. 55 is then ready for insertion and use in the trackway already described.. Ref..- erence to Figure 8 will indicateA the` positioning` of this modiiication of our invention. in the cabinet structure.

From the foregoing it will be seen thatV we have provided. a construction unique in design. simple of manufacture and` allowing'. great ease or manipulation. The provision of mechanism to allow removal of the swivel plate from thefarrn is considered to be of particular utility since it enables the user to conveniently transfer` volumes from one position to another without a: complete breakdown of the instrurrrenta-l-ities` employed. In avoiding the disadvantages of thermal-1y attempts in the prior art tol obtain alike result, it must be emphasized that our invention has succeeded innlling a need for a construction whereby'the topof a suitable cabinet support or table struc ture is unbroken and may therefore serve more than one purpose. Similarly, such topmay be horizontal, and the volume; rotated to any posi'-, tion thereupon', for inspectionV from' any angle.

It isobvious that this invention may lne-varied many ways and other expedients` employed to accomplish-the purposes thereof; however, it is to bel understood that our inventionisl only limited bythe scope of the following. claims'.
